Coastal Sediment Cell Boundaries For Western Australia

2026 data from the Department of Transport defines spatially discrete coastal sediment cells for Western Australia. These two-dimensional units represent natural management areas where sediment sources, sinks, and transport pathways are connected. The data is provided as map services for coastal process analysis.

Use Cases

• Map sediment transport pathways and cell boundaries for coastal erosion modeling using the spatial features.
• Analyze the intersection of sediment cell boundaries with jurisdictional lines for integrated coastal zone management.
• Identify sediment sources and sinks within defined coastal cells to inform beach nourishment projects.

Strengths

• Data is current, with a last update in March 2026.
• Sourced from the authoritative Coastal Information unit of the Department of Transport.
• Represents natural, physically-based management units that cross jurisdictional boundaries.

Limitations

• No tabular data or column schema is provided, limiting quantitative analysis.
• Data is specific to Western Australia (WA), not nationally representative.
• Available only as WMS and ArcGIS map services, requiring GIS software for access.
